Keep Your Home Healthy— If It’s in Your Crawl Space, It’s in Your Home


healthy home begins at the bottom. Many homeowners often ignore their home’s sub areas, such as basements and crawl spaces, until moisture causes costly structural and health problems. Neglecting these areas leaves your home open to a variety of pollutants. Crawl space encapsulation systems and basement drainage systems allow homeowners to address standing water issues to prevent future damage, and keep your family safe. Dirt crawl spaces are never-ending sources of moisture. Even if the dirt’s surface seems dry, digging down a few inches reveals moist earth. Moisture ruins houses by providing a hospitable environment for mold, fungi, and insects that destroy wood framing. Moisture in a crawl space affects not only the floor system directly above it, but also the entire house. Warm air in a heated building rises. As it rises, replacement air is sucked from the lowest part of the house – your house is actually sucking the ground. This natural air movement, called the stack effect, is how chimney’s work. Consequently, whatever is in the air at the lowest point eventually flows up into the living sections. Up to 40% of the air we breathe on the first floor of our home comes from the crawl space. To avoid moisture’s negative affects, a crawl space should be fully sealed and isolated from the ground and the outside. A new innovative

and effective method has been tested and perfected in numerous locations throughout the country and is now available to Portland and southwest Washington homeowners – the CleanSpace® Crawl Space Encapsulation System™ by Basement Systems Inc. This technique involves placing a 20-mil 7-ply sandwich of high- and low-density polyethylene with polyester-cord reinforcement on the dirt (or concrete) floor and up the walls. This pool-linerlike sheeting is made especially for this system and is treated with an antimicrobial finish that protects against mold and mildew growth on the liner. Lower energy loads, as a result of the encapsulation system, translates into a profitable return on the initial investment. It is strong enough to crawl on and store materials on, and is blue on the bottom and bright white on top to really brighten a crawl space, making it a relatively pleasant storage place. Many crawl space foundations leak. Such cases require a drainage system appropriate to the details of the crawlspace. Basement Systems, the makers of CleanSpace®, designed a tri-patented sump pump system, the SuperSump®, that works in conjunction with the liner to create an airtight seal to keep moisture and bugs out. The SuperSump features a built-in WaterWatch® alarm system to let you know if there is ever a pump or power problem before the crawl space floods. Just remember that your crawl space, although often neglected until

it’s too late, is one of the most important spaces in your home. It can be a spawning ground for mold, bugs, smells, odors, and radon gas. The moisture generated in the crawl space can lead to structural damage in your home and loss of energy. While on the other hand, a clean, sealed crawl space can be an extra source for much needed storage while making your home a healthy and safe one.

The CleanSpace® encapsulation system comes with a 25-year warranty against rips and tears, and from having groundwater on top of the liner. CCB#127319. Before
